Seawall Repair Products

Body - Seawall Repair ProductsIn most cases, seawall repair is NOT a DIY project. It’s important to find a qualified seawall repair specialist instead of a general contractor. In this article, we’ll explain the benefits of Seawall Repair Network® repair products when installed by our network of highly-trained preferred marine contractors.

SW-RP1: Seawall Repair Product for Sealing Leaks & Strengthening Soil

As mentioned in a previous blog post, What is SW-RP1? Why Do You Need It for Seawall & Bulkhead Repair? “The hallmark of Seawall Repair Network® is our proprietary SW-RP1 repair permeation solution. Simply put – it is the best product on the market for seawall soil stabilization. SW-RP1 is essential for sealing your seawall’s panel cracks, filling voids and defects behind your seawall, and perhaps most importantly, proving soil stabilization for your seawall. SW-RP1 transforms the surrounding soil of your seawall into a water-tight impermeable mass, which blocks the transference of energy and lateral stress caused by the typical build-up of hydrostatic pressure behind the seawall. SW-RP1 is environmentally safe and is certified to NSF (61-5) standards for contact with drinking water.

SW-RP6: Seawall Repair Product for Stabilizing Surrounding Soil

In the blog article SW-RP6: Soil Stabilization for Seawall Repair we explain that “SW-RP6 is ideal for stabilizing soil around ancillary structures during the seawall repair process. This comes into play with buildings, parking garages, roadways, and other infrastructure in close proximity to seawalls with soil loss and settlement. In cases like this, the Seawall Repair Network® contractor essentially creates chemical grout columns to provide stability. SW-RP6 is phthalate-free and NSF certified to NSF/ANSI/CAN 61 (approved for contact with drinking water).”

Seawall Repair Products for Concrete Preservation

From Seawall & Bulkhead Concrete Preservation: “Concrete is chemically formed through a process known as hydration/curing. Concrete deteriorates chemically under the influence of soil, water, and air-born contaminants, weathering action, and corrosion of the embedded steel reinforcement. Seawall Repair Network® offers a complete solution to prevent, restore, and protect steel-reinforced concrete by modifying its chemical and physical properties.” Click here for more information on  Seawall Preservation products.

Banner - Four Critical Warning Signs of Seawall Failure

Four Critical Warning Signs of Seawall Failure

Warning signs of seawall failure include: sunken soil near a seawall, rust stains on a seawall, cracked concrete, and movement or shifting.Corrosion, tides, boat wakes, tropical storms, and hurricanes can all contribute to seawall damage and, ultimately, failure. Additional causes undermine the structure on the landward side. Rainfall creates more hydrostatic pressure than rising and falling tides. Every time it rains or the irrigation system runs (and every time the tide goes out) all of the groundwater above the waterline needs a place to go. Massive pressure can build up if that water is trapped on the landward side, putting immense stress on the structure. (Read more in the article, How Soil Instability Causes Seawall Damage.) That is a recipe for seawall failure that can be avoided if you know the signs.

Sunken Soil Near a Seawall

Soil depressions appear due to the loss of soil near the structure. Water is seeping through or underneath the seawall, weakening the structure and contributing to soil erosion. Strong surrounding soil is critical to a healthy seawall.

Rust Stains on a Seawall

Rust stains are a sign of corroded rebar inside the concrete. Corroded rebar expands, cracking and destabilizing the structure.

Movement or Shifting

Hydrostatic pressure and/or lack of supporting soil around the structure can cause sections of the wall to move or shift over time.

Cracks in the Concrete

Cracks in the concrete can be caused by spalling due to rebar corrosion, or movement due to hydrostatic pressure and unstable soil.

Additional Signs of Seawall Failure

  • Blocked or clogged weep holes (vents that are used for draining landward side water build-up to relieve hydrostatic pressure).
  • Sand or soil deposits at the bottom of the wall panel joints on the water side. This indicates sediment seeping through the joints from the landward side.
  • Damage to structures up to 100 feet away. Water infiltration on the landward side can expand a great distance when proper venting/drainage is not occurring.  Look for sinkholes, depressions, and/or sunken concrete in the general area surrounding the seawall.

Seawall Repair Network’s Proprietary Repair Process

Let’s review the proprietary repair process used by Seawall Repair Network’s preferred marine contractors. First, crews perform deep injections of SW-RP1 repair material directly behind each panel joint in the seawall. This process fills all the voids while permeating and strengthening the soil. The permeated soil becomes as hard as crystalline bedrock. Next, a new pressure relief system is created by coring through weep hole channels and the layer of resin that has been installed behind them. These new channels extend through the permeated soil and into the soil on the landward side. Proprietary pressure release technology is then installed to regulate the release of hydrostatic pressure from any new water that may form behind the wall in the future. Because pressure release technology also stops landward-side soil from passing through the dewatering channels, it prevents new erosion and void formations. If needed, seawall preservation treatments can also be applied to the concrete. The support of high-strength SW-RP1 repair material, combined with the regulation of hydrostatic pressure and concrete preservation treatment protects the seawall from subsequent movement, damage, or failure.

Seawall Repair Case Studies

Body - Seawall Repair Case StudiesMother nature’s oceans, lakes, and rivers can be so beautiful and calm but over time her natural forces will cause damage and eventual failure to seawalls and bulkheads. These complicated structures are made up of a variety of essential components. If one component fails, the entire structure is at risk. In traditionally constructed seawalls, weep holes with a geotextile fabric filter allow water to flow from the landward side back into the ocean to prevent pressure buildup.

So what causes a seawall to fail? Over time, as the filter fabric fails, soil migration creates voids behind the wall, which causes structural instability. As the voids behind the wall fill up with water, hydrostatic pressure behind the seawall causes the wall panels to shift over time. The shifting panels damage the seawall cap, which holds the entire structure together. When this happens, failure of the seawall is imminent. If ignored, these problems only get worse. Water is relentless but we can be too.

Professionally trained contractors armed with Seawall Repair Network’s proprietary repair process have repaired all kinds of seawalls in a wide variety of locations. Here are a few case studies…

Shoreline Protection with Curtain Grouting

Body - Shoreline Protection with Curtain GroutingWaterfront property can be expensive to own and maintain. If you own a property on an open waterfront, you are likely dealing with the forces of nature eroding away at your land and the unreasonable complexity that comes with finding a trustworthy party to inspect and preserve your investment.

We know searching for waterfront preservation solutions can be extremely difficult to begin, and often seems to require a costly construction commitment. Our team has spoken with open waterfront property owners of all kinds, and the stress is undeniable regardless of their background. Our goal is to mitigate the stress and uncertainty that comes with protecting your shoreline against erosion and instability. Seawall Repair Network is the only nationwide network of shoreline preservation professionals offering innovative and cost-effective solutions to protect open coastal, lake, and riverfront properties where shoreline preservation is critical and a waterfront barrier is not existent.

Is Waterfront Barrier Construction Critical?

Protecting your shoreline with the construction of a waterfront barrier structure such as a seawall, bulkhead, and/or revetment is one option, but not the only option. Seawall Repair Network professionals are capable of injecting subgrade “seawalls” beneath the shoreline by permeating the soil with environmentally safe curtain grouting material SW-RP6.

Shoreline Curtain Grouting with SW-RP6

This is done by systematically injecting SW-RP6 soil stabilization material deep into the ground which solidifies the existing soil into a single, solid lightweight mass that is resistant to erosion. This newly formed subgrade curtain wall extending across the length of the shoreline prevents further soil migration and washout.

Revetment and Rip Rap Repair

Body - Revetment and Rip Rap RepairAccording to the U.S. Army Corps of Engineers, a revetment is defined as: “A facing of erosion resistant material such as stone or concrete that is designed to protect a scarp, embankment, or shoreline feature against erosion.” The key feature of a revetment structure is that it prevents erosion of landmass. This feature is critical for waterfront property owners and managers. One major problem associated with revetments, seawalls, and bulkheads is that these structures are often reliant on a filter layer that engineers specify in the design plans prior to construction. Often this filter layer (a.k.a. filter fabric or membrane) fails prematurely, and a massive loss of soil results in structural instability of the structure.

Pictured in this article is a revetment made of rip rap (small boulders) that protects the shoreline alongside property managed by a homeowners association in Pompano Beach, Florida. A recent assessment performed by Seawall Repair Network member contractor Stable Soils (located in Ocala, Florida) determined that the structure’s filter fabric had failed, causing soil migration from the landward side into the water, and gradual sinking of the structure. The technicians at Stable Soils are experts with Seawall Repair Network’s proprietary repair material (SW-RP1) and stabilization procedures. They were able to permanently shut down the soil migration, fill all related voids, stabilize the rip rap, and save this structure from a very costly failure.

Seawall Repair – Lake of the Ozarks, Missouri

Case Study: Seawall Repair in Lake of the Ozarks, Bulkhead Repair Lake of the Ozarks, Revetment Repair Lake of the Ozarks.A homeowner on the Lake of the Ozarks in Missouri reached out to Seawall Repair Network member contractor RT Construction after noticing soil erosion behind their seawall. This particular seawall was constructed with stacked stones that had been mortared together. Over the years, some of the stones broke loose and fell out, leaving gaps in the wall. Water poured through these gaps and eroded soil on the landward side of the wall, creating large voids behind the structure. In addition, the old drainage system that had been installed with the wall in order to prevent water buildup on the landward side was no longer working.

Repair Materials

The primary repair material used by Seawall Repair Network contractors is SW-RP1. This material is ideal for stabilizing soil, filling voids, and stopping leaks. Once a seawall is airtight, it’s important to install panel filters to prevent hydrostatic pressure from building up on the landward side due to accumulated rainwater. Panel filters allow water in the soil to drain through to the other side of the wall in a controlled manner.


On the landward side of the wall, the crew began by inserting a half-inch injection rod to a depth of about 1 foot below the mud line (the point at which the bottom of the lake intersects with the seawall). SW-RP1 was then injected, the rod raised a little, more material was injected, and so on until that area behind the seawall was stabilized. This process was repeated every few feet along the back of the wall until the entire 100 foot seawall was reinforced and sealed up. Next, the crew installed panel filters between each injection location, allowing for water drainage into the lake and preventing any future damage from hydrostatic pressure.


This entire repair job on all 100 feet of the seawall was completed in only two days. The property owner could see the visible improvements (sealed holes in the wall, filled voids in the soil, brand new panel filters installed) and was very happy with the results.

Seawall Repair in Carrollton, GA

Body - Seawall Repair in Carrollton, GAA homeowner on a private lake in Carrollton, Georgia contacted Seawall Repair Network looking for a way to save their failing seawall. A representative from member contractor Ground Consolidation Solutions promptly arrived to perform a free assessment. There was significant soil loss on the land side. In addition, the seawall itself was starting to shift due to a buildup of hydrostatic pressure.

Repair Materials

SW-RP1 repair material and hydrostatic pressure control panels were used to stabilize the seawall and prevent any further shifting.


Given that there were two separate issues occurring, a two-pronged repair approach was in order. First, the crew backfilled the soil voids with coarse river sand, then they injected SW-RP1 repair material from the bottom of the seawall up to the top. This ensured that all of the leaks were sealed off. In addition, the SW-RP1 resin permeated the soil, creating a solid mass to add structural support. Next, the crew addressed the hydrostatic pressure issue. Hydrostatic pressure occurs when groundwater on the soil side builds up and has nowhere to escape, putting undue pressure on the seawall. To alleviate this pressure, the crew installed panel filters every 6 feet, along the face of the seawall just above the average water line. The filters allow water to pass through from the landside without any soil loss.


This process took only two days to complete and was completed for a fraction of the cost of seawall replacement.
